Latest Patents:

Kazuhiko Funato holds two notable patents that reflect his dedication to advancing engine technology. The first, titled **Double air-fuel ratio sensor system in internal combustion engine**, presents a sophisticated system that includes two air-fuel ratio sensors positioned upstream and downstream of a catalyst converter. This design enables precise adjustments to the actual air-fuel ratio based on outputs from both sensors. The system also features a diagnostic capability to assess catalyst converter deterioration based on downstream sensor data, ensuring optimal performance while prohibiting detection during abnormal upstream sensor states.

The second patent, known as **Method of discriminating octane number of fuel for motor vehicle**, addresses the critical issue of engine knocking by managing ignition timing. Funato's invention computes a basic ignition advance angle with a correction value that allows for optimal ignition timing adjustment. If the octane number of the fuel is deemed insufficient for engine performance, the system intelligently retards the ignition timing, thereby preventing potential engine damage and ensuring smoother operation.
